What are the precautions for the structural design of plastic mold manufacturers

However, the protective film is relatively good after use, and the main reason for the development is that the protective film is protected and shows unnecessary shrinkage, and the same PE protective film is used in the manufacturing process. The temperature difference in the environment, the effect of use and the bonding process are designed to avoid unnecessary stretching. The construction of the module library is mainly composed of two parts. The construction of the module library consists of three stages: module classification, structural feature model and custom feature creation. The plastic mold standard part is a special case of the modules that exist in the module library. Yes. Definition requires only two steps, whereas module partitioning is a modular design step.

1. Mix the silicone and curing agent evenly. The appearance of the molded silica gel is a fluid liquid, component A is silica gel, and component B is a curing agent. Example: Take 100g of silica gel and add 2g of hardener, which will affect the life of the silicone mold and the number of times of turning over the mold, and the mold may be discarded.

Plastic Mold Structure Co., Ltd. has a variety of tools that can make people more convenient in modern life. In order to beautify plastic products, plastic molds usually need to be polished before mass production. Otherwise, plastic products and product launches are troublesome. The finish is also glossy. For example: laptops, chargers, fans, etc. Therefore, some details should be paid attention to when polishing the plastic mold, otherwise the service life of the mold will be shortened.

In Plastic Mold Structure Co., Ltd., the no-flow injection molding method refers to the adiabatic heating method using convection channels, and there is no injection system when taking out the mold by keeping the plastic melted between the nozzle cavities of the injection molding machine. Material. The former is called adiabatic euro injection molding, and the latter is called hot runner injection molding.

A certain amount of metering is pre-adjusted to apply additional injection pressure (secondary or third injection pressure) depending on the filling conditions of the mold so that a small amount of melt (buffer volume) remains on the screw tip near the end of the injection stroke. Add a little to dissolve. In this way, compression of the product can be prevented or shrinkage of the article can be accommodated.

Advantages of plastic mold system compared with other molds: Plastic mold injection products have higher density, dimensional temperature and mechanical strength than ordinary injection products, and the electrical performance can reach the level of compression molded products. After the molding material is plasticized in the barrel, the cavity is filled by screw injection, and the second stage is the compression molding stage, in which the parting surfaces are tightly bonded under a certain pressure, and then the pressure is maintained and solidified. After molding, the mold is opened and the product is removed. The structure of the plastic mold is actually very complicated, but its advantages cannot be ignored.
